Owens being shoehorned into rivalry
Kevin Owens and Seth Rollins had a great rivalry which culminated in a WrestleMania match. Now when Rollins has issues with Rey Mysterio, it made little sense to bring KO back.
There was nothing wrong in the segment between KO and Rollins, it just felt forced that Owens wanted to be included in a fight that he had no part to play in.
